turned on.
Key: HBASE-22931
URL: https://issues.apache.org/jira/browse/HBASE-22931
Project: HBase
Issue Type: Improvement
Affects Versions: 3.0.0
Reporter: Yiran Wu
In a large cluster, there are many tables and regions. META tables will be
scanned frequently after opening space quota. We need optimize it to support
larger cluster.
some code...
{code:java}
for (TableName table : Iterables.concat(tablesWithTableQuotas,
tablesWithNamespaceQuotas)) {
// Don't recompute a table we've already computed
if (tablesToRemove.contains(table)) {
continue;
}
final int numRegionsInTable = getNumRegions(table);
// If the table doesn't exist (no regions), bail out.
if (numRegionsInTable == 0) {
if (LOG.isTraceEnabled()) {
LOG.trace("Filtering " + table + " because no regions were
reported");
}
tablesToRemove.add(table);
continue;
}
